Abstract (en)
[origin: EP2000973A2] [PROBLEMS] To reduce the required amount of program codes when processing the whole image in a one-dimensional SIMD parallel image processing system having a smaller number of PEs than the number of pixels in the width direction of the image to be processed. [MEANS FOR SOLVING PROBLEMS] A controller 2 for controlling a PE array 1 includes a command repetitive-execution part 22, which includes an operand converting part 221, a memory address converting part 222, and an operation code converting part 223. When a command fetching/decoding part 21 reads and executes program codes stored in a program memory 3, the repetitive-execution part 22 determines the program codes to cause the operand converting part 221, memory address converting part 222 and operation code converting part 223 to perform conversions in accordance with the command, thereby performing a repetitive execution of the one-command program description adaptive to a plurality of related pixels assigned to the PEs, whereby the program code amount can be reduced.
